  1. Remove Teflon sealing rings from valve sleeve using small-bladed knife. See Figure . DO NOTΒ  scratch sleeve seal grooves. Wrap worm end of sleeve in shop towel and mount in soft-jawed vise. Place Mandrel (T75L-3517-A1) from seal installation kit on sleeve. Install one valve sleeve Teflon ring over mandrel.
  2. Using Pusher (T75L-3517-A2), rapidly push down on pusher, forcing Teflon ring down mandrel cone and into fourth groove of valve sleeve. Repeat procedure for 3 more rings, adding another Spacer (T75L-3517-A3) under mandrel for each ring to line up with next open groove.
  3. After all sleeve rings are installed, remove installation kit. Apply light coat of power steering fluid to sleeve and Teflon rings. Reinstall one Spacer (T75L-3517-A3) on input shaft as a pilot for Sizing Tube (T75L-3517-A4). Slide sizing tube carefully over valve sleeve Teflon rings. Ensure rings are not being deformed when tube is slid over rings.
  4. Allow sizing tube to sit over rings for minimum 5 minutes to help contract Teflon rings. Remove sizing tube. Ensure rings turn freely in grooves. Install sleeve into control valve assembly soon after removing sizing tube.
